Question 1

How long does it take for Utrogestan to start working?

Accepted Answer

The sedative effects can be felt within hours of taking a dose. For endometrial protection, the full transformation occurs over the course of a 12‑day cycle; withdrawal bleeding typically appears 2‑7 days after completing the course.

Question 2

Why is Utrogestan taken at bedtime?

Accepted Answer

Utrogestan can cause drowsiness and dizziness due to its neurosteroid metabolite allopregnanolone. Taking it at bedtime minimises daytime impairment and helps with sleep quality.

Question 3

Does Utrogestan cause weight gain?

Accepted Answer

Some women experience mild fluid retention and appetite changes, leading to a small weight change. Unlike some synthetic progestins, natural progesterone has less effect on appetite and body composition.

Question 4

Can I take Utrogestan if I have a peanut allergy?

Accepted Answer

No. Utrogestan contains soybean lecithin, and there is cross‑reactivity with peanut allergy. You should not take this medicine and should discuss alternative progestogens with your doctor.

Question 5

Does Utrogestan protect against breast cancer?

Accepted Answer

No. Combined HRT (estrogen + progestogen) is associated with a small increase in breast cancer risk after several years of use. Utrogestan is not protective against breast cancer; regular breast screening is essential.
